Specification of Letters Patent.

Application filed April 19, 1912. Serial lie/691,905.

To all whom'it may concern Be it known that I, Gconcn H; l lonxgacitizen of the United States, residing at Vesper, in the county of d andState of Wisconsin, have invented a new and useful Silo, of which thefollowing is a specification.

silos.

The object of-the present invention is to improve, the constructionofsilos, ni'iire'""'es-"" the door opening and of producing a uni formtension on the binding rods or hoops,

and of enabling the same to be tightened wlthout the use of a wrench, orother special tool.

novel combination of parts hereinafter fully described, illustrated inthe accom ianying drawing, and pointed out in the claims heretoappended; it being understoodthatvar1'- I ous changes in the form,proportion, size and minor details ofconstruction, within the scope ofthe claims, may beresorted to Without departing from the spirit orSflCll:

'ficing any of the advantages of the invention.

.In the drawing: Figural is an elevation of a .portion of a sil'oshowing one of the binding rods or hoops and an adjusting device,constructed in accordance with this invention. Fig. 2 is ahorizontal-sectional viewof the same. Fig. 3 is a detail perspectiveview of one of the plates.

L1 e numerals of reference designate corresponding parts in all thefigures of the drawing. i

In the accompanying drawing in which is illustrated the preferredembodiment of the invention, the adjustable connection comprises in itsconstruction a pair of approxi- L-shaped plates 1, secured to the staves2 of a silo at opposite sides of a door opening 3, and receiving theterminal portions of a hoop or binding rod 4. The L- shaped plate ormember consists of an outer attaching wing or portion 5 and an inweirdlyextending transversely disposed en- The invention relates toimprovements in With these and other objects in view, theinvention'consists in the construction and gaging flange 6,. which fitsagainst the edge of the stave 2 at the dooropening 3. The outerattaching plate or portion 5, which is provided at opposite sides withperforations 7 for-the reception of screws 8, or other suitablefastening devices for securing the plate to the stave 2, has alongitudinal open ing 9 extending through a horizontally roundedenlargement 10, and receiving the terminal portions of the hoop 4;. Theouter -attaching portion of the plateispreferably reinforced at the endsof the enlargement by ribs or bosses 11, and the inwardly extendingstave engaging flange or portion (3,

tends from the outer face of the stave 2 to the inner face thereof.

The terminal portions of the binding rodor hoop {L extend through theopenings 9, which are horizontally alined, and the said terminalportions project beyond-the plates 1 and extend partially across thedoor opening 3, being spaced apartat the central portion thereof. TheendslQ of the binding rod or hoop are threaded to receive nuts 13,-preferably rectangular and arranged in a longitudinal slot or opening Idof a t-urn buckle 15. The turn buckle is composed of spaced sides andconnecting end portions 16, provided with smooth bores or openings 17for the reception or" the terminal portions of the binding rod or hoop.The inner faces of the sides of the turn buckle are parallel, and thenuts snugly fit within the slot or opening 14. and are adapted to besimultaneously rotated when a guide or way for the nuts, which areslidably interlockedwvith the turn buckle. The ends 16 of the turnbuckle are tapered and fit against the L-shapedplates at. the inner endsof the enlar einents of the attaching portions, and the turn buckle spaes the said plates and maintains a door opening of a peri'nanent width.

The hook or binding rod is yieldably maintained in engagement with thestaves of the silo by means of a pair of coiled springs 18, arranged onthe terminal per tions of the hoop or binding rod and housed within theend portions of the longitudinalL interposed between the nuts 13 and theends 16 and adapted to be compressed by the said nuts= When the turnbuckle is rotated, the coiled springs are simultaneously adjusted theturn buckle is turned.

-which is' impert'orate, is tapered and eit- By this arrangement,

maintained on the ends of the binding rod or hoop at each side of thedoor opening 3,

to vary their tension and to produce the desired pressure on the stavesof the silo. a uniform tension is and the turn buckle may be readilyrotated by inserting a stick or similar implement in the'central portionof the longitudinal slot or opening 14.

While only one binding rod or hoop is illustrated in the accompanyingdrawing, the rods or hoops of a silo'will be arranged in the usualmanner, and the adjusting devices for the same will be locatedsufficiently close to form a ladder at the door opening. What is claimedis 1. In combination with a silo having a door opening, a binding rod orhoop having threaded terminal port-ions projecting at the door opening,plates secured to the exterior of the silo at opposite sides of the dooropening and having portions extending into I the same and arranged toengage the edges of the staves of the silo at the door opening, saidplates being also provided with horizontal openings through which theterminal portions of the binding rod or hoop pass, a turn buckleextending across the door opening and bearing against the said platesand receiving the terminals of the said rod or hoop, nuts mounted on thethreaded terminal portions of the binding rod or hoop, and coiledspringsdisposed on the latter and arranged to be compressed by the nuts.

2. In combination with a silo having a door opening, a binding rod orhoop hav- 'ing threaded terminal portions pro ecting at the saidopening, approximately *L- shaped plates consisting of exterior portionssecured to the'outer faces of the staves of the silo at opposite sidesof the door opening, and inwardly pro ecting flanges engaging the edgesof the staves at the said Gopies of this patent may be obtained foropening, said plates being provided with horizontally alined openingsthrough which the binding rod or hoop passes, a turn buckle extendingentirely across the door opening and fitting against the said plates andreceiving the terminal portions of the binding rod or hoop, nutsslidably interlocked with the turn buckle and engaging I the threadedportions of the binding rod or hoop, and opposite springs arranged to besimultaneously compressed by, the nuts. 3. In combination with a silohaving a door opening, a binding rodvor hoop having threaded terminalsprojecting at the door opening, exterior plates secured to the silo atopposite sides of the opening and having inwardly extending portionsengaging the edges of the staves at the said opening, said plates beingalso provided with openings through which the "binding rod or hooppasses, and a turn buckle extending entirely i across the door openingand fitting against the said plates and tudinal opening and havingsmooth bores at the ends thereof through which the terminals of thebinding rod or hoop engaging the threads of the terminal portions of thebinding rod or hoop and slidably arranged in the longitudinal opening,and coiled springs disposed on the terminal portions of the binding rodor hoop and interposed between the nuts and the ends of the turn buckleand located within the opening of the latter and adapted to be providedwith a long1-' simultaneously adjusted by the rotary movement ot theturn buckle.

In testimony, that I claim the foregoing as my own, I have hereto,affixed mysignature in the presence of two witnesses.
